Description
Die Erfindung geht aus von einem Verfahren zum Betreiben eines Heckscheibenwischers eines Kraftfahrzeugs und einer Vorrichtung zur Durchführung des Verfahrens nach der Gattung der unabhängigen Ansprüche. Aus der Bedienungsanleitung Volvo 850, Seite 1:11 ist die Steuerung einer Heckscheibenwischanlage beschrieben, wonach beim Einrücken eines Lenkstockschalters als Bedienelement der Wischanlage Scheibenwischer und Waschvorrichtung gemeinsam eingeschaltet werden. Beim Loslassen des Lenkstockschalters ist vorgesehen, daß der Heckscheibenwischer noch zwei oder drei Wischzyklen nachläuft. Dieser relativ lange Nachlauf ist insbesondere bei kurzzeitiger Wisch-Waschbetätigung unnötig lang und führt auf trockener Scheibe zu einem verstärkten Verschleiß des Wischgummis.The invention is based on a method for operating a rear window wiper of a motor vehicle and one Device for performing the method according to the type of independent claims. From the instruction manual Volvo 850, page 1:11 is the control of one Rear window wiper system described what after engaging a steering column switch as a control element of the wiper system Windscreen wiper and washer switched on together become. When the steering column switch is released provided that the rear wiper two or three Wiping cycles continue. This is a relatively long wake unnecessary, especially for brief wiping operations long and leads to a reinforced one on a dry disc Wear of the squeegee.
Ferner ist es bei einer Heckscheibenwischanlage bekannt, mit einem Lenkstockschalter beispielsweise die Vorgaben eines Dauerwischens, eines Wisch-Waschens sowie eines Intervallwischens zu ermöglichen. Aus Kostengründen werden die beiden Funktionen Intervallwischen und Heckwaschen sowie die Waschwasserpumpe auf einen gemeinsamen Schaltkontakt des Lenkstockschalters gelegt. Die Waschwasserpumpe wird demnach auch beim Ein- und Ausschalten des Intervallbetriebs kurzzeitig aktiviert. In Abhängigkeit von dem in Wasserschlauch vorhandenen Wasser sowie von der Aktivierungszeit fördert die Waschwasserpumpe das Waschwasser auf die Heckscheibe. Befindet sich beim Ausschalten des Intervallbetriebs der Wischarm im Rücklauf zu einer Parklage, so wird das Waschtwasser neben dem Wischarm auf die Heckscheibe gefördert. Nach dem Erreichen der Parklage bleibt der Wischarm stehen, weil der Intervallwischbetrieb ausgeschaltet wurde. Das geförderte Waschwasser verläuft nun auf der kurz zuvor trockengewischten Heckscheibe.It is also known in a rear window wiper system with a steering column switch, for example, the specifications of a Continuous wiping, wiping and one To enable interval wiping. For cost reasons the two functions interval wiping and rear washing as well the wash water pump on a common switch contact of the Steering column switch placed. The wash water pump is accordingly also when switching the interval mode on and off activated briefly. Depending on the in Water hose existing water as well as from the The wash water pump promotes activation time Wash water on the rear window. Located at Switch off the interval operation of the wiper arm in the return to a parking location, so the wash water next to the Wiper arm conveyed to the rear window. After reaching the wiper arm stops in the park position because of the Intermittent wiping has been switched off. The funded Wash water now runs on the just before dry wiped rear window.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Betreiben eines Heckscheibenwischers eines Kraftfahrzeugs und eine Vorrichtung zur Durchführung des Verfahrens anzugeben, die die genannten Nachteile vermeiden.The invention has for its object a method for Operating a rear window wiper of a motor vehicle and an apparatus for performing the method specify that avoid the disadvantages mentioned.
Die Aufgabe wird durch die in den unabhängigen Ansprüchen angegebenen Merkmale jeweils gelöst.The task is defined in the independent claims specified characteristics solved in each case.
Das erfindungsgemäße Verfahren zum Betreiben eines Heckscheibenwischers eines Kraftfahrzeugs weist den Vorteil auf, daß mit einfachen Mitteln ein ausreichendes Trockenwischen der Heckscheibe trotz einer Mehrfachbelegung eines Bedienelements, bei der gleichzeitig Wisch- und Waschfunktionen ausgelöst werden, möglich ist. Erfindungsgemäß ist vorgesehen, daß nach dem Abschalten des Heckscheibenwischers durch das Bedienelement zunächst das Erreichen der Parklage des Wischarms mittels eines Parklagesignals erfaßt wird und daß damit ein weiterer Wischzyklus, ausgehend von einer Parklage des Wischarms bis zum erneuten Erreichen einer Parklage ausgelöst wird. The inventive method for operating a Rear window wiper of a motor vehicle has the advantage on that with simple means a sufficient dry wipe the Rear window despite multiple occupancy of one Control element, at the same time wiping and Washing functions are triggered, is possible. According to the invention it is provided that after switching off the Rear window wiper by reaching the parking position of the Wiper arms is detected by means of a parking signal and that thus another wiping cycle, starting from a parking position of the wiper arm until it is reached again a parking situation is triggered.
Mit diesen Maßnahmen ist es möglich, den weiteren Wischzyklus unabhängig davon auszulösen, ob sich während des Abschaltens der Wischarm gerade in der Packlage oder auf dem Weg dorthin befindet. With These measures make it possible to continue the wiping cycle regardless of whether triggered during the shutdown the wiper arm is currently in the pack position or on the way there located.
Die erfindungsgemäße Vorrichtung zur Durchführung des Verfahrens weist den Vorteil auf, daß teilweise bereits vorhandene Mittel verwendet werden können, um die neuen Funktionen zu realisieren. Vorgesehen ist eine signalverarbeitende Anordnung, der ein von einem Parklagensensor abgegebenes Parklagensignal sowie das von dem Bedienelement abgegebene Schaltsignal zugeführt sind. The inventive device for performing the The method has the advantage that some already Existing funds can be used to build new ones Realizing functions. One is planned signal processing arrangement, one by one Parking position sensor emitted parking signal and that of the switching signal emitted are fed.
Die signalverarbeitende Anordnung enthält Speichermittel zum Hinterlegen eines Abschaltsignals sowie eine UND-Verknüpfung, der das gespeicherte Abschaltsignal und das Parklagensignal zugeführt sind. Wird in der UND-Verknüpfung festgestellt, daß ein gespeichertes Abschaltsignal vorhanden ist, und daß das Parklagensignal gleichzeitig aufgetreten ist, dann erzeugt die signalverarbeitende Anordnung ein Einschaltsignal für den Heckscheibenwischerantrieb für einen weiteren Wischzyklus.The signal processing arrangement contains storage means for Storage of a shutdown signal and an AND link, the the stored shutdown signal and the Parking signal are supplied. Is in the AND link found that a stored shutdown signal is present is, and that the parking signal occurred at the same time then the signal processing arrangement generates a Switch-on signal for the rear window wiper drive for another wipe cycle.
Eine besonders vorteilhafte Maßnahme sieht vor, daß die signalverarbeitende Anordnung in den Heckscheibenwischerantrieb integriert ist. Zusätzliche Leitungen zu den bereits heute vorhandenen Leitungen sind mit dieser Maßnahme vermeidbar.A particularly advantageous measure provides that the signal processing arrangement in the Rear window wiper drive is integrated. Additional Are lines to the existing lines avoidable with this measure.
Als Parklagensensor ist eine herkömmliche Kontaktscheibe geeignet, die in der Massenproduktion besonders preiswert herstellbar ist und ihre Zuverlässigkeit bewiesen hat.A conventional contact disk is used as a parking position sensor suitable, which is particularly inexpensive in mass production is producible and has proven its reliability.
Weitere vorteilhafte Weiterbildungen und Ausgestaltungen sowohl des erfindungsgemäßen Verfahrens als auch der erfindungsgemäßen Vorrichtung zur Durchführung des Verfahrens ergeben sich jeweils aus den weiteren abhängigen Ansprüchen und aus der folgenden Beschreibung.Further advantageous developments and refinements both the inventive method and the Device according to the invention for performing the Procedures arise in each case from the further dependent claims and from the following description.

dienendes
Steuersignal 20 für den Heckscheibenwischerantrieb 11, das
gleichzeitig ein Löschsignal 20' ist, welches dem
Abschaltsignalspeicher 18 zugeleitet wird. Weiterhin stellt
die signalverarbeitende Anordnung 14 ein zweites
Steuersignal 21 für die Waschwasserpumpe 13 bereit, das
vorzugsweise identisch ist mit dem Schaltsignal 17. Die in
Figur 1 gezeigte Verbindung innerhalb der

Das erfindungsgemäße Verfahren zum Betreiben eines Heckscheibenwischers eines Kraftfahrzeugs wird anhand des in Figur 2 gezeigten Flußdiagramms eines Verfahrens näher erläutert:The inventive method for operating a Rear window wiper of a motor vehicle is based on the in Figure 2 shown flowchart of a method closer explains:
Das in Figur 1 gezeigte Blockschaltbild eines
Heckscheibenwischers eines Kraftfahrzeugs zeigt nur die für
die Durchführung des erfindungsgemäßen Verfahrens
erforderlichen Teile. Diejenigen Teile, die zum Betreiben
des Heckscheibenwischers gemäß dem eingangs angegebenen
Stand der Technik erforderlich sind, enthält Figur 1 dagegen
nicht. Beispielsweise kann das Bedienelement 16, das
vorzugsweise als Lenkstockschalter in einem Kraftfahrzeug
ausgebildet ist, mehrere Schaltkontakte enthalten, die
sowohl ein Bereitstellen des ersten Steuersignals 20 für den
Heckscheibenwischerantrieb 11 sowie ein Bereitstellen des
zweiten Steuersignals 21 für die Waschwasserpumpe 13
auslösen. Insbesondere kann mit dem Bedienelement 16 im
allgemeinen ein Intervallbetrieb des
Heckscheibenwischerantriebs 11 ausgelöst werden. Sofern
zusätzliche elektronische Funktionen, beispielsweise der
Intervallbetrieb zu realisieren sind, können die dafür
erforderlichen Teile ohne weiteres in der
signalverarbeitenden Anordnung 14 enthalten sein. Eine
einfache Unterbringung der zusätzlichen Funktionen in der
signalverarbeitenden Anordnung 14 ist insbesondere möglich,
wenn die UND-Verknüpfung 19 sowie gegebenenfalls der
Abschaltsignalspeicher 18 in einem Mikroprozessor realisiert
sind, der problemlos weitere Aufgaben wahrnehmen kann.The block diagram shown in Figure 1

Für die Erfindung wesentlich ist das Erkennen des
Schaltsignals 17 in der Bedeutung eines Abschaltsignals.
Während der Betätigung des Bedienelements 16, bei der eine
Bedienperson beispielsweise einen Intervallbetrieb des
Heckscheibenwischers ein- oder ausschaltet, wird bei
bekannten Anlagen gleichzeitig das zweite
Steuersignal 21 für die Waschwasserpumpe 13 bereitgestellt.
Befindet sich nun beim Abschalten der Wischarm 10 gerade in
seiner Parklage oder auf dem Weg dorthin, kann der Fall
auftreten, daß das von der Waschwasserpumpe geförderte
Waschwasser auf den bereits gewischten Teil der Heckscheibe
trifft. Das erfindungsgemäße Verfahren sieht vor, daß nach
dem Auftreten des Schaltsignals 17, das einem Abschalten
entspricht, der Wischarm 10 einen weiteren Wischzyklus,
ausgehend von einer Parklage bis zum erneuten Erreichen
einer Parklage durchführt.The recognition of the is essential for the
In einem ersten Schritt des Verfahrens, dessen Flußdiagramm
in Figur 2 gezeigt ist, wird deshalb in einer erster Abfrage
22 festgestellt, ob das Schaltsignal 17 mit der Bedeutung
eines Abschaltens aufgetreten ist. Falls dies nicht der Fall
ist, wird zur ersten Abfrage 22 zurückgegangen. Falls doch, wird
in einem zweiten Verfahrensschritt zur zweiten Abfrage 23
weitergegangen. Das Auftreten des Schaltsignals 17 mit der
Bedeutung des Abschaltens wird im Abschaltsignalspeicher 18
festgehalten. In der zweiten Abfrage 23 wird gestgestellt,
ob der Wischarm 10 eine Parklage erreicht hat. Beim
Erreichen der Parklage gebt der Parklagensensor 12 das
Parklagensignal 15 an die signalverarbeitende Anordnung 14
ab. Falls auch die zweite Abfrage 23 mit Ja zu beantworten
ist, wird in einer Anweisung 24 durch Bereitstellen des
ersten Steuersignals 20 für den Heckscheibenwischerantrieb
11 ein weiterer Wischzyklus des Wischarms 10 ausgelöst. Das
Erfüllen der beiden Abfragen 22, 23 kann mit der in der
signalverarbeitenden Anordnung 14 enthaltenen UND-Verknüpfung
19 festgestellt werden, die das erste
Steuersignal 20 bereitstellt. Identisch mit dem ersten
Steuersignal 20 ist das Löschsignal 20', das den
Abschaltsignalspeicher 18 löscht. Dieser Schritt ist in
Figur 2 als zweite Zuweisung 25 bezeichnet. Bei der in Figur
1 gezeigten Realisierung, bei der das erste Steuersignal 20
identisch ist mit dem Löschsignal 20', werden die erste und
zweite Zuweisung 24, 25 gleichzeitig ausgeführt.
Anschließend kehrt das Verfahren zurück zur ersten Abfrage
